User interface for analysis of electrocardiograms

Abstract

The present invention relates to a computer-implemented method for electrocardiogram analysis, the method comprising the steps of receiving at least one ECG signal; analyzing the ECG signal to provide features and / or identify at least one episode and / or event, wherein an episode is a segment of the ECG signal defined by a starting time, a duration and a label obtained during the analysis of the ECG signal and an event is a strip of the ECG signal of predefined duration defined by a starting time and a label obtained during the analysis of the ECG signal; and displaying a multiple field display (1) which includes at least a main plot (42), being a global view of a graphic representation of the ECG signal in a first time window; a local view of a graphic representation of the ECG signal in a second time window (51), where the first time window comprises the second time window; an intermediate view of a graphic representation of the ECG signal in a third time window (52), wherein the third time window comprises the second time window and has a duration comprised between the duration of the first time window and the duration of the second time window

Description

FIELD OF INVENTION[0001]The present invention pertains to the field of cardiology. In particular, the invention relates to the analysis of electrocardiographic data using a graphical user interface.BACKGROUND OF INVENTION[0002]Cardiac Holter monitoring devices (often simply Holter) are portable electrocardiographic devices for cardiac monitoring (the monitoring of the electrical activity of the cardiovascular system) for long time lapses (ranging from several minutes to several weeks). The data recorded by these devices is analyzed by professionals for the diagnosis of heart activity abnormalities, including arrhythmias such as atrial fibrillation. Guaranteeing an exact diagnosis requires an extensive analysis of the large amount of data available. The aim of an interface for long duration electrocardiographic (ECG) recordings is to improve the efficiency of the analysis and diminish the time consumption of such a task. The amount of data collected by an Holter device in a standard ...

AI Technical Summary

Benefits of technology

The patent describes a display that shows ECG data to physicians in a way that includes relevant local views and a global view. This helps improve diagnostic accuracy. The display lets the user access global information in a long time window and detailed information about the ECG signal in a shorter window of time. This combination of different time scale plots makes it easier for the user to understand the ECG signal and interpret it quickly.

Problems solved by technology

The amount of data collected by an Holter device in a standard ambulatory use is large and the classical analysis performed by the clinician, who has to visually analyze the whole duration of the electrocardiographic (ECG) recordings, is inefficient and time consuming.

Furthermore, these types of platforms generally require a high computation power which is unpractical and the results of the analysis are only available locally on the platform which produced the analysis.
